Abstract
Over the past few decades, concrete-filled steel tubular (CFST) columns have gained increasing popularity in building construction, due to their significant structural and economic benefits over conventional steel and reinforced concrete columns. In addition to the extensive studies into the short-term behaviour of CFST columns, there have been some experimental programs carried out to investigate the long-term behaviour of CFST columns with normal-strength materials. Very limited research, however, has been performed to investigate the long-term behaviour of CFST columns with high-strength steel tubes. Therefore, this paper presents a preliminary study that aims to investigate the creep and shrinkage behaviour of CFST tubes made with high-strength materials through finite element analysis. Verification of the proposed finite element model is achieved by comparing with independent experimental results. The effects of various design parameters that might affect the creep and shrinkage behaviour of composite columns are evaluated through the verified finite element model.
